2. Vitamin A
Load up on foods like sweet potatoes, kale, mangoes and carrots to get the antioxidant benefits of vitamin A. Retinol, one of the only FDA-approved wrinkle treatments, is a form of this vitamin, which works inside cells, hitting receptors which helps them function as if they were younger. It also slows the breakdown of collagen, Farris says, which is important in giving skin its youthful appearance and elasticity. While it’s important to get your vitamin A in your diet to keep a strong immune system and keep our skin and eyes healthy, it can also be applied topically for anti-aging benefits.

3. Vitamin D
When it comes to anti-aging, don’t neglect your bone health. Bone loss can be one of the more powerful effects of aging to consider, especially for women, Farris says. Vitamin D works with calcium to keep your bones strong and dense. “One of the things that makes your face look saggy is loss of bone. We focused for years on collagen, and now we understand that you lose fat, collagen and bones in aging,” she said. “The better your bone health, the better your bone structure is and the more youthful you will appear.”

Foods like fatty fish, some dairy products and egg yolks are good sources also. According to the NIH, most Americans get the majority of their vitamin D from fortified foods, like most milk and some orange juices.

While vitamin D synthesis also occurs from our daily sun exposure, sunscreen with SPF 8 and higher can block that effect. The American Academy of Dermatologyrecommends getting vitamin D from your diet, as unprotected sun exposure can damage your skin and cause premature aging.

4. Vitamin K
Load up on leafy greens to get your vitamin K, especially if you complain about bruising. Farris says one of the most common complaints she gets from her post-50 patients is of bruising, commonly on the arms. Vitamin K helps keep collagen in your skin intact and keeps your skin thick, reducing the appearance of bruises, veins and, as some suggest, even dark circles.

5. Vitamin E
Vitamin E is great, especially when combined with vitamin C, in keeping your cells healthy. Vitamin E helps fight damaging free radicals on a cellular level, which protects your cells from vulnerability. Farris says it’s one of the most potent antioxidants out there. It can help provide sun protection to the skin and may have anti-inflammatory benefits. It is fat-soluble and can be found in many oils, such as sunflower oil and soybean oil, as well as in nuts and seeds.
